It’s not a sign of much, but major European states are enjoying a growing “remittance economy” sector. What began as a curiosity to travel has clearly grown into a need to find that job wherever that job is found. In a highly regulated job market, that also means abroad.
The IMF study goes into this a bit further, saying that these remittances TO the developed world are a meaningless percentage of their GDP. However, the phenomenon does say something about overgovernance, overregulation, and to governments trying to "manage economies" in various degrees.
